The use of rotifer communities to provide a preliminary national classification of small water bodies in England. Correlation coefficients r 2 and P value P of the environmental variables and Rotifera and Copepoda species through the Canonical Correspondence Analysis, using 1, permutations. In the second canonical variable, T. In Irai Reservoir, L of subsurface 30 cm water were filtered using a motor pump which is widely used to sample zooplankton, and in Rio Verde Reservoir, samples were obtained through vertical hauls filtering about L of water.

Primary copepofos in lakes and reservoirs is controlled by a set of physical, chemical and biological variables Thornton, For Rio Verde Reservoir, details of physical copepodso chemical variables are found in Cunha et al. Low diversity of zooplankton in the river mouth of a eutrophic reservoir SP, Brazil: Several studies provided lists of rotifer species that are indicative of different trophic states, among them good indicators of eutrophic conditions are Bra-chionus sp.

Species identification was based on specialized literature e. Although phytoplankton biomass increases with water residence time, other factors are important in determining biomass accumulation.

In oligotrophic environments, higher frequency of T. International Institute of Ecology. However, even with the trend observed in the present culgivo, the use of rotifers as bioindicators must be careful due to the contrasting results that can be found in the literature. Probably due the excessive eutrophication with intense algal blooms and other variables such reservoir morphometry, climate and altitude, Thermocyclops was present but was never dominant during the studied period.

The continental zooplankton is composed of rotifers, small crustaceans cladocerans and copepods and protozoans.

Another example is the study of Bonecker et al. Species diversity of planktonic and epiphytic rotifers in copepldos backwaters of the Delhi segment of the Yamuna River, with remarks on new records from India. Spatial and temporal variation of limnological features, Microcystis aeruginosa and zooplankton in an eutrophic reservoir Funil Reservoir, Rio de Janeiro.

Potential use of Cyclopoida Crustacean, Copepoda as trophic state indicators in tropical reservoirs.

Composition and abundance of zooplankton in the limnetic zone of seven reservoir of Paranapanema river, Brazil. Seasonal changes in the vertical distribution of rotifers in a eutrophic shallow lake whit cuptivo states of clear and turbid water.

The same is observed for some species of Metacyclops genera. Oecologia Australis, 15 3: Blackie, London, pp. Among copepods, only M. Zooplankton especially crustaceans and rotifers as indicators of water quality.

Irai Reservoir has a residence time of days. The canonical correspondence analysis showed more satisfactory results for copepods than for rotifers, associating T.

All presupposes of these analyses were reached. The species that showed significant differences between reservoirs are shown in Table 2. Zooplankton assemblages may be considered bioindicators of eutrophication, as they are coupled to environmental conditions, responding more rapidly to changes than do fishes, and are easier to identify than phytoplankton. In both reservoirs, diversity and richness were higher at station 2, and abundance at station 1.

Zooplankton assemblages Copepoda and Cladocera in a cascade of reservoirs of a large tropical river SE Brazil. Coopepodos, in this period, 65 species of phytoplankton from nine families were identified.

Assessment of the trophic state of a restored urban lake based on zooplankton community estructure and zooplankton-related indices. The climate is Cbf, according to Koeppen classification Maack, Se escogieron aquellas especies que presentaron las mayores diferencias.

Copeoodos between phytoplankton and zooplankton biomass in large lakes. During a year, monthly samplings were carried out in three stations in each reservoir.

In China, Xiong et al. Thus, only the high richness of Brachionidae can be pointed out as indicator of eutrophic conditions, even considering the other relationships commonly found in the literature.

Water samples were taken to the laboratory for determination of nitrogen Mackereth et al. A minimum of individuals were counted per sample.
